gemini-cli-deep-research

Use when the user wants to launch a Deep Research investigation — phrasings include "research X", "do a deep dive on Y", "investigate Z", "give me a comprehensive report on W", or any request for a multi-source synthesis that will take 10–30 minutes. Refines vague prompts into well-scoped research questions, suggests an appropriate output format (Executive Brief, Technical Deep Dive, Market Analysis, Comprehensive Research Report, or custom), helps the user pick file-search-store grounding when relevant, and then calls research_start with an outputPath so the report writes itself when the job completes.
